\caption{Observational parameters for narrow-band \ha~photometric observations
  and the TAURUS Fabry-P\'erot interferometry for NGC~6951, NGC~3359 and
  NGC~1530. Seeing is taken as the {\it FWHM} measured in the final continuum-subtracted \ha~images of unsaturated stellar sources and the seeing for Fabry-P\'erot observations 
is the {\it FWHM} of the continuum images obtained from the analysis of the data 
cubes and the spectral resolution is the velocity separation between adjacent planes in the data cube.}\label{tabparamobs}
